HEDDLE "FRAME.

Application filed February 25, 1928. Serial N o..256,83 1.

' The object of the invention is to provide improvements in textilemachinery, andmore particularly heddle frames for looms.

Another and more specific object is to provide in heddle frames meansfor stiffening the oppositely positioned rails and for supporting theheddle bars at one or more regions intermediate their end portionswherev their main support is provided.

A further object is to provide an improved stay rod connecting theoppositely positioned rails of the frame to prevent them from springingor flexing out ofa predetermined relation with ea chother, and toefficiently sup port the usual heddle bars intermediate their ends andprevent their becoming curved or bent, which would permit the bank orseries of heddles carried thereby to become shifted at the center out oftheir common plane.

Still another object'is to'provide a simple yet highly efficientconnection between the re-- spective rails of the frame and the ends ofthe stay rod, whereby the latter effectually resists any tendency of theformer to move either toward or away from each other, at the same timepermits the ready disengagement ofthe rod from the frame members.

And a still further object is to provide a stay rod of this characterwith a substantially centrally positioned apert-ur e,'opening laterallythrough one edge and so shaped as to permit the ready insertion of aheddle bar and prevent its accidental removal laterally therefrom, yetpermitting the disass ociation of said rod and bar in a predeterminedmanner;

Vfith these and other objects inmind, the present invention comprisesfurther details of construction and operation, which are fully broughtout in the followin g description when read in conjunction with theaccompanying drawings in which Fig. 1'is a front elevation of a heddleframe comprising top and bottom rails and heddle bars connected by astay or brace embodying and secured in position by features comprisingthe present i'nx' e'ntion'; Fig. 2 is an enlarged fragmentary portion ofthe device as shown in Fig. 1" and partly in section; Fig. 3 is avertical section on the line 33 of Fig; 2; and Fig. 4 is a perspectiveview of the lower end portion of the improved stay rod. I

Referring to the drawings, a heddle frame is here shown as comprisingparallel oppositely positione'd top and bottom rails land 2,

connected at their ends by anysuitable means su'chas straps 3.Heddle'supportingbars 1 and 5 extend longitudinally of the frameparallel with and spaced slightly from the neighboringframe'rails 1 and2, and operatlvely supporting a bank or series of heddles 6, which areattached thereto in any wellknown manner.

The stay rod in the present instance is preferably a metal strap whichextends transversely in aplane perpendicular to the plane of the rails 1and 2 and comprisesva central portion 7 which adjacent to its oppositeends is bent angularly to provide feet 8 bifurcated bycentrallypositioned slots 9, which extend longitudinally inwardly fromthe respective ends of the red, the terminal portions 10 of each footbeing angularly bent in opposite directions so as to be in alignmentwith each other and therefore substantially parallel with the centralportions 7.

In their adjacent surfaces. the respective rails '1 and 2 are providedwith recesses 11,

terminating in one direction in shoulders 12 and in the oppositedirection in other shoulders 13, between whichshoulders are normallypositioned the end portions or feet 8 of to provide ofi-sets 14, toreceive the toes or terminal portions 10 of said feet;

Each .of said rails is'furthermore provided with a bolt 15,extendingtherethrough, and

[the stay rod, while-adjacent to said lasti named shoulders, saidrecesses are deepened in substantial alignment with each other,v

each bolt having ahead 16'a-dapted to engage the normally outer surfaceof'oneof the feet 8,'while each bolt is also provided beneath its headwith an enlargement 17, which is smaller than the head but larger incross section than the shank of the bolt, being also of greater extent;in one direction than in other, so as to fit snugly within the slot 9 ofthe foot, to prevent the latter from turning.

This bolt also normally secures the foot witliin the recess 11, theadjacent toes 1.0 within the deeper off-set 14, and the foot as awholebetween the shoulders 12 and 13. r

Itwill also be notedthat the stay rodad- 'jafcent to its end portions isprovided with centrally disposed apertures 18, through which the heddlebars are adapted to extend,

each of said apertures being guarded by a finger 19 to prevent abaraccidentally escapingtherefrom, but opening laterally beyond the freeend of said finger to permit the ready removal of the bar through theoutlet 20 when desired.

With this construction, the stay rod is normally secured in operativeposition by the bolts 15 and is prevented from turning by theenlargements 1'? within the foot slots 9, and from movement with respectto said rails by the shoulders 12 and 13 in cooperation with the boltsthemselves. However, to detach the stayrod from the frame rails, saidbolts upon being loosened and moved longitudinally towards each otherpermit the respectively adjacent foot to be freed from said bolts andfrom the rails, upon effectively shortening the rod or the distancebetween its ends by bending or flexing it centrally at the same timepermitting relative movement of the heddle bars towards the open ends ofthe apertures 18, whence they too are freed from engagement with thestay red.

It will also be noted that the foot termini are tapered by convergingthe transverse ly opposite sides thereof, said termini being adapted tobe drawn by the attaching means 15 into the body or" the framen'ien'ibers 1 and 2, when only the major portions 11 of the recesses are[)IOVlflGtl tor reception of the angular-1y disposed feet 8. in any suchcase the toes or termini 1O tend also to contract the slots 9 andthereby bind tighter the enlaro'ed )ortions 17 of said attachin means Vm h lo, and positively prevent even a slight axial oscillation of saidrods.

-. Having thus described my invention, what I claim and desire toprotect by Letters Patent of the United States is r 1. In a heddleframe, the combination of a rail having a recess defined by oppositelypositioned shoulders, with a stay rod having a bifurcated angularlydirected end portion positioned in said recess between said shonlders,and means engaging said rail and extending; through the bifurcatedportion or said rod to normally secure said rail and said rod inoperative relation, said means when loosened permitting said. rod to beseparable therefrom by moving said end portion transversely of? theadjacent portion of said means.

2. In a heddle frame, the combination of a rail. having a recess inturn. having an ottset portion. with a sta red having a bit catod footsection positioned in said recess and having: an angular y bent portionextending into said oli'set portion, and fastening means extendingthrough said rail and through the bifurcation of said foot section toprevent the accidental separation oi said rail from said roe, said meanswhen loosened a rail, with :1 st

permitting said rod to be released therefrom by longitudinal movementor" said foot section transversely of the foot-engaging portion of saidmeans.

In a heddle frame, the combination of a rail having a recess in turnhaving an offset portion, with a stay rod terminating in an angularlybent toot divided by a slot and positioned in said recess, the portionsof said foot upon opposite sides of said slot being singularly bent withrespect to said foot and being positioned in said otl'-set, andfastening means extending through said slot and having a transverselyenlarged portion engaging the opposite sides of said slot to preventsaid rod and said means from turning axially.

4. In a heddle frame, the combination of a rail havinga recess definedby oppositely positioned shoulders and in turn having an oil-setportion, with a stay rod terminating in an angularly bent foot dividedby a slot and positioned within said recess between said shoulders, thedivided terminal portions of said foot being angularly bent with respectto said foot'and normally positioned in said recess oii-set, and a boltextending through said rail and having a transversely enlarged portionengaging the opposite sides of said slot to prevent said rod and saidfoot from turning axially and to prevent said foot from beingaccidentally withdrawn lon gitudinally from said recess.

5. In a heddle frame, the combination of a rail having a recess definedby oppositely positioned shoulders, with a stay rod terminating); in anangular-1y bent foot divided by a slot and positioned within said recessbetween said shoulders, and a bolt extending through said rail andhaving a transversely enlarged portion engaging the opposite sides ofthe slot to prevent said rod and said bolt from turning axially and toprevent said foot from being accidentally withdrawn longitudin ally fromsaid recess.

6. in a heddl'e frame, the combinationof rod comprising a rectilinearbody portion extending at an angle to said rail and a footportion havinga slot and positioned para lel with said rail, and fastening; meanscarried by said rail and extending through said slot'in said foot tonormally secure said toot and said rail together, said toot and saidrail being: separable by relative longitudinal. movement of said tootand transverse movement oi the teething-agingportion of said means.
